We consider a simple form of pricing for crowdsourcing system, where policy is published priori, and workers then decide their task acceptance. Such widely adopted in practice its simplicity, e.g., Amazon Mechanical Turk, although additional sophistication to rule can enhance budget efficiency. With the goal designing efficient rules, we study impact following two design features policies: (i) ...

wind energy today, has attracted widespread interest from among a variety of sources of renewable energy in the world. owing to the increasing demand for production of electrical energy for electricity networks by using wind power, it is essential that wind power plants are actively incorporated in the network’s performance using an appropriate control system. in general, these wind power plant...

for multi-objective optimal reactive power dispatch (morpd), a new approach is proposed where simultaneous minimization of the active power transmission loss, the bus voltage deviation and the voltage stability index of a power system are achieved. optimal settings of continuous and discrete control variables (e.g. generator voltages, tap positions of tap changing transformers and the number of...

The main goal of the present study is testing asymmetric risk pricing and comparing it with pricing of traditional risk measures in Tehran Stock Market. Accordingly, a sample consisting of 101 companies listed in Tehran Stock Market during 2002-2013 went under investigation. In order to test asymmetric risk pricing, regression model of panel data was applied. The results revealed a positive and...

Although technological progress has lowered the cost of solar and wind to make renewable energy competitive with fossil fuels on a levelized-cost basis, supply of these resources is highly variable and inelastic, which contrasts with elastic, stable and controllable supply from traditional power plants. As a result, the cost of flat retail pricing in comparison to dynamic, marginal-cost retail ...

Distribution of distributed generation resources in distribution systems has several advantages, including reducing losses, improving voltage profiles, reducing pollution, and increasing system reliability. However, one of the most important points regarding the placement of these resources in distribution networks is economic issues and the return on investment and the increase in profits from...

This study presents an optimal framework for the operation of integrated energy systems using demand response programs. The main goal of integrated energy systems is to optimally supply various demands using different energy carriers such as electricity, heating, and cooling. Considering the power market price, this work investigates the effects of multiple energy storage devices and demand res...
